Full reset
Perform a full reset only when the HP Jornada does not respond
to a soft reset. A full reset erases all data you have entered,
including all files, system settings, and programs you have
installed. If you have forgotten your password, you also need to
perform a full reset.
Performing a full reset erases all files, programs, and data you
have entered. You can restore only data that has been backed
up to your desktop PC or CompactFlash Card. (For more
